Borussia Dortmund chief executive Hans-Joachim Watzke has admitted that Manchester United and City target Mats Hummels can leave the club in the summer but only if interested clubs meet their valuation. There is likely to be a bidding war for the Germany international's services in the summer, with a number of clubs from across Europe interested in acquiring the defender's services.

The 27-year-old defender, who will have just one-year remaining on his current deal at the end of the season, has already admitted that he is facing the biggest decision of his career this summer as he ponders whether to extend his stay at the Signal Iduna Park Arena or make a move to another club in the summer.

Hummels' father Hermann has already indicated that Bayern Munich are one of the clubs interested but the Bavarian giants are likely to face competition from the two Manchester clubs along with other clubs from Europe for his signature. The club's chief executive has now made it clear that they will not stand in the defender's way if a substantial offer is made by an interested club and is confident that they will backed by the player, who he believes is happy to stay and see out the remainder of his deal if an agreement is not reached.

"To forbid Hummels to leave would be small-minded," Joachim Watzke said, as quoted by Goal.com. "We have to accept that someone playing for Dortmund for eight years and getting [close to] 28 starts to think about his situation."

"If the club isn't ready to pay a lot of money, he has a contract in Dortmund. And I am sure that he has no problem with continuing playing for Dortmund," the Bundelsiga club's chief explained.

Joachim Watze, meanwhile, is confident that the club can replace any player that they lose during the summer transfer window. Ilkay Gundogan has been linked with a potential switch to Manchester City, who will be managed by Pep Guardiola next season, while Pierre-Emerick Aubameyang and Henrikh Mkhitaryan have also been linked with summer moves.

"No matter what a player decides, the past five years have shown that we can replace every player. We have always found solutions and will find solutions again," he added, as quoted by ESPN FC.
